I am a postdoc based at Laboratoire de Mathématiques d’Orsay (LMO, Université Paris-Saclay), working in the group of Thibault Lefeuvre. I received my Ph.D. from Purdue University, under the supervision of Plamen Stefanov and Gunther Uhlmann. Previously, I obtained my bachelor's and master's degrees from Pontificia Universidad Católica de Chile, under the supervision of Mariel Sáez Trumper.

Research
So far, my research has focused on hyperbolic dynamics, Riemannian and Lorentzian geometry, and elliptic partial differential equations. I am particularly interested in rigidity questions (inverse problems) in these topics. I enjoy using tools of microlocal and semiclassical analysis.
